■
NOTE If the system is configured according to pattern A,
nor the remote controller room thermostat
function (default OFF if multiple set point is
selected) nor the external room thermostat (as
replacement of the remote controller room
thermostat function) may be used.
■
The remote controller water temperature value is
ignored when pattern A is active.
■
It is the installers responsibility to make sure no
unwanted situations can occur (e.g. too high
water temperatures towards floor heating loops,
etc.).
■
It is the installers responsibility to make sure the
water circuit is well balanced (e.g. when a
domestic hot water request occurs, there will be
sufficient flow towards other appliances as well,
etc.)
■
Daikin does not offer any temperature reducing
device (
possibility to use multiple set points.
■
It is advised to only use the automatic storage
functionality for domestic water heating when
applying pattern A (with a high set point
temperature).

). This system only provides the
Multiple set point control according to pattern B
The basic setup of multiple set point pattern B is the same as a
normal classic design, so again no domestic water heating and space
heating is possible simultaneously.
Multiple set point pattern B is focused on space heating operation
and allows using multiple water set points in combination with the
remote controller or external room thermostat.
The configuration of pattern B allows 3 space heating set points and
1 domestic hot water set point.
The request signals for space heating can be implemented in 2
different ways (installer choice):
■
thermo ON/OFF signal (from external room thermostat)
Space 1 Space 2
TRD TRD
■
status signal (active/not active) from the corresponding
temperature reducing device

Space 0, not using a temperature reducing device (
needs to be linked with the highest water temperature set point and
can be controlled by the remote controller room thermostat function
or by the external room thermostat. Settings for space 0 can be made
on the remote controller (same as during normal operation
(1) When using the automatic weather dependent function for setting of space 0, you
have to make sure that the lowest possible temperature of the space 0 floating
set point (including the possible negative shift value) is higher than the
temperature set point of spaces 1 and 2.
This means that field setting [3-03] of space 0 needs to be higher than
temperature set point of spaces 1 and 2.
